Serial No. 212,920.

This invention relates to the building art and particularly to a method and means for attaching plaster board in place on studding used in connection with the building of walls. Apparently the only practical and economical way of applying plaster board to the metal studding used in the walls of class A fire proof building is that specifically set forth in Patent No. 1,579,377, owned by the assignees of this present invention. -Vi here this method is employed the outer edges of the plaster lath are of course firmly attached to the studs and to each other. In many cities however it is'required by the building ordinances that the lath be fastened securely to the studs at least every six inches along the length of the stud. Since most oi the commercial lath is cut a foot or more in width the conditions under such ordinances require that the lath be provided with an intcrmediate fastening element, as for instance that type shown in Patent No. 1,619,97. This type can be made to do the work nicely under certain conditions but it was found in commercializing it that where the studs were set against a dead wall and like conditions it was a difficult matter to insert and tie the wires clear around the studs.

To overcome the objections noted above we have therefore devised a fastener and method or applying same so that the erector, working only from the front face of the wall, may adequately fasten and secure the lath to and across the studs without having to work the fastening elements clear around the stud.

A. further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reterence indicate corresponding parts in the several views:

Fig. 1 is aperspective view or a fragmentary section of a Wall showing the applicathereagainst.

tion of our improved method to the erection of a wall and showing our. improved fastening elements in place.

Fig. 2 is a sectional view of a stud and a piece of lath showing the first step in the application of the fastening element.

Fig. 3 is a similar View showing the next step.

Fig. l. shows the fastening elementin its final set position to hold the lath secured in position against the stud.

liig. 5 is a similar view to Fl 4 but showing the lath as applied to both sides of the stud.

Fig. (3 is a iug element.

l-leierring now more particularly to the diameters of reference on the drawings, the numeral 1 designates the stud and 2 the plasterboard lath; A the fastening element per so, and B a tightening wedge.

The fastening element comprises a flat face piece 3 having spaced sharpened prongs 4 bent at substantially right angles thereto. One prong 4 has an inner hook 5 thereon.

In the application of our improved method to the erection of a wall the lath strips 2 are laid promiscuously across the studs 1 as indicated in said Patent No. 1,579,377, the abutting ends being secured to each other and to the edges of adjacent strips by the clips 6.

As the strips areila'id across the studs 1 it is necessary that they be fastened to the stud in whatever point they chance to rest To accomplish this we employ the fastening elements A. These are interposed between the adjacent edge of the strips or pressed through the body thereof at desired points, as shown clearly in the drawings. The prongs 4 are pressed past the edges of the stud 1 until the hook 5 alines with the inner face of one of the legs of the channel of the stud as shown clearly in Fig. 2. Then with any formot tool found adaptable the flat face 3 is crimped together to draw the hook 5 into engagement with the adjacent leg 1 of the stud and to cause the opposite prong to frictionally engage the flat back of the stud, all as disclosed in Fig. 3. The wedge 13 is then driven into place between perspective view of the fastenthe face of the lath strip and the flat face 3 of the fastening element and wedges all the elements tightly together.

As. indicated in the preamble to this specificationthe main objective of this invention is of course to be able to set and secure the lathing in place against the studs from working only from the front face of the wall. Hence While we have described in detail a specific type of fastening element, still in practice it may be found that various deviations from such detail may be resorted to without departing from the spirit of the invention, as defined by the appended claims.

Having thus described our invention what we claimas new and useful and desire to secure by Letters Patent'is:

' 1. A fastening element for the purpose disclosed comprising a member having a pair of spaced. sharp pointed prongs, and a hook on one prong.

2. A fastening element for the purpose disclosed comprising a member having a pair of spaced sharp pointed prongs, anda fiat web connecting ,the prongs, the flat of the web lying in a plane at right angles to the flat of the prongs.

3. A fastening element for the purpose disclosed comprising a member having a pair of spaced prongs, having a connecting web and a wedge element to fit back of the Web and between the. prongs.

4:. A fastening element for the purpose described comprising a member having a pair of spaced sharp pointed prongs, and a hook on one prong inwardly of its sharp point.

5. A fastening element for the purpose described comprising a pair of flat prongs the flat of the prongs lying in the same plane,

a flat web connecting the prongs, the flat of the web lying in a plane at right angles to the plane of the flat of the prongs.

6. A fastening element for the purpose described comprising a pair of prongs, and a normally straight but bendable web con necting the two, one prong normally extending at right angles to the web and the other prong normally extending at an obtuse angle thereto relative to the first prong.

In testimony whereof we aflix our signatures.
